How to share files from a android device to IPhone workout computer

Hi I’m on the move so I don’t have access to a computer.Earlier on I simply used to use a third party app or inbuilt app to share huge files and it would be done in a matter of seconds but now when I’m using an iPhone to share among iOS users it’s fine but to share to non Android users its a bloody mess.

I seriously wonder the purpose of Bluetooth when you can’t even use it to share files to-from all other devices.

I am looking sr something on the lines of snapdropdotnet but for bigger files this thing takes eons and is stuck with transferring message for many minutes
